FIELD

The present disclosure relates to sternal closure devices andinstrumentation.

BACKGROUND

This section provides background information related to the presentdisclosure and is not necessarily prior art.

Surgeries are often performed on humans and animals to treat disease orinjury. Such surgeries can result in the surgeon having to repair aseparated, cut or fractured bone. In the case of an injury, the surgeonmay need to immobilize and fix two or more bone portions together toallow the bone to heal over time. Treating certain diseases, such asheart disease, for example, often requires the surgeon to cut apatient's sternum to gain access to and perform a procedure on thepatient's heart. Once the heart procedure is complete, the cut sternummay be repaired by immobilizing and joining the separate portions of thesternum together to allow the sternum to heal over time. It is oftendesirable to apply a compressive force urging the bone portions togetherto facilitate healing of the bone.

It will beapparent to those skilled in the art that specific details need not beemployed, that example embodiments may be embodied in many differentforms and that neither should be construed to limit the scope of thedisclosure. In some example embodiments, well-known processes,well-known device structures, and well-known technologies are notdescribed in detail.

The terminology used herein is for the purpose of describing particularexample embodiments only and is not intended to be limiting. As usedherein, the singular forms “a,” “an,” and “the” may be intended toinclude the plural forms as well, unless the context clearly indicatesotherwise. The terms “comprises,” “comprising,” “including,” and“having,” are inclusive and therefore specify the presence of statedfeatures, integers, steps, operations, elements, and/or components, butdo not preclude the presence or addition of one or more other features,integers, steps, operations, elements, components, and/or groupsthereof. The method steps, processes, and operations described hereinare not to be construed as necessarily requiring their performance inthe particular order discussed or illustrated, unless specificallyidentified as an order of performance. It is also to be understood thatadditional or alternative steps may be employed.

When an element or layer is referred to as being “on,” “engaged to,”“connected to,” or “coupled to” another element or layer, it may bedirectly on, engaged, connected or coupled to the other element orlayer, or intervening elements or layers may be present. In contrast,when an element is referred to as being “directly on,” “directly engagedto,” “directly connected to,” or “directly coupled to” another elementor layer, there may be no intervening elements or layers present. Otherwords used to describe the relationship between elements should beinterpreted in a like fashion (e.g., “between” versus “directlybetween,” “adjacent” versus “directly adjacent,” etc.). As used herein,the term “and/or” includes any and all combinations of one or more ofthe associated listed items.

Although the terms first, second, third, etc. may be used herein todescribe various elements, components, regions, layers and/or sections,these elements, components, regions, layers and/or sections should notbe limited by these terms. These terms may be only used to distinguishone element, component, region, layer or section from another region,layer or section. Terms such as “first,” “second,” and other numericalterms when used herein do not imply a sequence or order unless clearlyindicated by the context.

Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,”“lower,” “above,” “upper,” and the like, may be used herein for ease ofdescription to describe one element or feature's relationship to anotherelement(s) or feature(s) as illustrated in the figures. Spatiallyrelative terms may be intended to encompass different orientations ofthe device in use or operation in addition to the orientation depictedin the figures. For example, if the device in the figures is turnedover, elements described as “below” or “beneath” other elements orfeatures would then be oriented “above” the other elements or features.Thus, the example term “below” can encompass both an orientation ofabove and below. The device may be otherwise oriented (rotated 90degrees or at other orientations) and the spatially relative descriptorsused herein interpreted accordingly.

With reference to FIG. 1, a closure system according to the principlesof the present disclosure is generally identified with reference numeral10. The system 10 is depicted operatively associated with a sternum 12of a human body. The sternum 12, as shown, has previously undergone amedical procedure known as median sternotomy. As a result of thisprocedure, the sternum 12 has been severed, thus permitting a physicianaccess to tissues and/or organs located in the patient's thoraciccavity. However, the sternum 12 has since been reapproximated such thatthe previously severed portions 12 a, 12 b are now bound together by thesystem 10.

With continued reference to FIGS. 1-10, the system 10 may include acerclage or band 14, a bracket 16, and a tensioning device 18. As shownin FIG. 2, a needle 20 may be temporarily attached to a first end 22 ofthe band 14. The needle 20 may be attached to the first end 22 mayfasteners and/or a press or snap fit, for example. A second end 24 ofthe band 14 may be fixed to the tensioning device 18. The band 14 may bea flat, elongated and flexible member formed from a metallic materialand/or a polymeric material, for example. In some embodiments, the band14 could include a braided material. The band 14 may include a pluralityof parallel slots 26 formed therein. In some embodiments, a sleeve 28(FIGS. 2 and 3) may receive a portion of the band 14. In someembodiments, the sleeve 28 may be molded over the band 14 or otherwiseintegrally formed therewith.

The bracket 16 may be a plate formed from a metallic and/or polymericmaterial and may include a body portion 30 and a plurality of legs 32extending outward from the body portion 30. The bracket 16 may berelatively flexible to enable the bracket 16 to conform to the contoursof the sternum 12 when the bracket 16 is fastened thereto (as shown inFIG. 1). The body portion 30 may include an opening 34 extendingtherethrough. The opening 34 may allow the bracket 16 to be readily cutusing band cutters, for example, or other standard operating room toolsin case the sternum 12 needs to reopened after installation of thesystem 10. The body portion 30 may also include a plurality of tabs 36that cooperate to define a channel 38 through which the band 14 isslidably received. Each of the plurality of legs 32 may include one ormore apertures 40 extending therethrough. Self-tapping threadedfasteners 42 may extend through the apertures 40 and may threadablyengage the sternum 12 to fix the bracket 16 to the sternum 12 (as shownin FIG. 1).

The tensioning device 18 may include a receiver 44 and a tensioningscrew 46. The receiver 44 may include a body portion 48 and a tab 50. Asshown in FIG. 5, the body portion 48 may include a recess 52, a firstopening 54 and a second opening 56. The first and second openings 54, 56may be generally adjacent each other and are in communication with therecess 52. The tab 50 may extend outward from the body portion 48 andmay fixedly engage the second end 24 of the band 14. The second end 24may be received within a slot 58 (FIG. 5) in the tab 50 and may be fixedtherein by pins, welding, crimping, and/or one or more fasteners, forexample, or any other suitable means.

As shown in FIG. 5, the tensioning screw 46 may include a head portion60 and a stem 62. The head portion 60 may include threads 64 and one ormore slots 66 that can receive the tip of a screwdriver. The headportion 60 may be received in the recess 52 of the receiver 44 so thatthe stem 62 extends through the first opening 54 of the receiver 44. Asshown in FIG. 5, the second end 22 of the band 14 may be insertedthrough the second opening 56 and the recess 52 of the receiver 44. Thethreads 64 of the tensioning screw 46 may engage the slots 26 in theband 14 such that when the tensioning screw 46 is rotated relative tothe receiver 44, the band 14 is moved up or down (relative to the frameof reference of FIG. 5) relative to the receiver 44 based on thedirection that the tensioning screw 46 is rotated.

With continued reference to FIGS. 1-10, a method will be described forattaching the system 10 to the sternum 12 and tensioning the band 14 toreapproximate the sternum 12. With the needle 20 attached to the firstend 22 of the band 14 (as shown in FIG. 2), the first end 22 of the band14 may be looped around the posterior side of the sternum 12 so that theband 14 substantially circumscribes the sternum 12. Once the band 14 islooped around the sternum 12, the needle 20 may be removed from the band14, and the first end 22 of the band 14 may be inserted up through thereceiver 44 (as shown in FIG. 5). As shown in FIG. 1, the bracket 16 maybe positioned so that the fracture separating the two portions 12 a, 12b of the sternum 12 is visible in the opening 34 in the bracket 16(i.e., so that the two of the legs 32 of the bracket 14 are aligned withone portion 12 a, 12 b of the sternum 12 and the other two legs 32 arealigned with the other portion 12 a, 12 b of the sternum 12).

The tensioning device 18 may be used to tighten the band 14 around thesternum 12 to bind the portions 12 a, 12 b of the sternum 12 together.As described above, the tensioning screw 46 may be rotated relative tothe receiver 44 to move the band 14 up (relative to the frame ofreference of FIG. 5) to tighten the band 14 around the sternum 12 to adesired amount. Once the band 14 has been tightened to the desiredamount, the first end 22 of the band 14 may be trimmed (as shown in FIG.6) and subsequently folded over onto the tab 50 of the receiver 44 (asshown in FIG. 7).

With the band 14 sufficiently tightened around the sternum 12, thebracket 16 may be fixed to the sternum 12 with the fasteners 42. Thatis, the fasteners 42 may be inserted through the apertures 40 in thebracket 16 and driven into the sternum 12 using a screwdriver (e.g., amanual screwdriver or an electric screwdriver). As shown in FIGS. 8 and9, a fixture 68 may be employed to hold the fasteners 42 as they aredriven through the apertures 40 and into the sternum 12. The fixture 68may include a plurality of tubes 70 having apertures 72 sized to receivethe fasteners 42. The tubes 70 may have the same spacing and relativeorientation as that of the apertures 40 so that the fixture 68 can bealigned relative to the bracket 16 such that the apertures 72 arealigned with the apertures 40 (as shown in FIG. 8). With the fixture 68in this position, a screwdriver 74 (FIG. 9) can drive the fastenersthrough the apertures 72, 40 and into the sternum 12.

While the system 10 is described above as including the bracket 16, itwill be appreciated that the band 14 and tensioning device 18 could beused without the bracket 16 to reapproximate the sternum 12.

With reference to FIG. 11, another closure system 110 is provided. Thesystem 110 may include a band 114, a bracket 116, and a tensioningdevice 118. The structures and functions of the band 114, bracket 116and tensioning device 118 may be similar or identical to that of theband 14, bracket 16 and tensioning device 18 described above, apart fromany exceptions described below and/or shown in the figures. Therefore,similar features may not be described again in detail.

The band 114 may include a first end 122 and a second end 124. The band114 may extend through a slot 119 formed in the tensioning device 118.The second end 124 may include an enlarged portion or loop 125 thatprevents the second end 124 from sliding through the slot 119. In thismanner, interference between the loop 125 and the slot 119 fixes thesecond end 124 relative to the tensioning device 118 when the first end122 is pulled taught by tensioning screw 146 of the tensioning device118. Like the bracket 16, the bracket 116 may include a body 130 and aplurality of legs 132. Instead of tabs 36, the body 130 may include aplurality of ribs 133 that define a channel 138 through which the band114 is received.

The second end 324 of the band 314 may be fixed in the second slot351 by pins, welding, crimping, and/or one or more fasteners, forexample, or any other suitable means.

A periphery of the head 347 of the locking cam 345 may include a flatportion 354 and a round portion 356. The tab 346 may be a generallyL-shaped member having a first leg 358 and a second leg 360 (FIG. 15).The first leg 358 may be disposed between the head 347 and the axial endof the recess 348 and may include an aperture 362 through which theshaft 349 of the locking cam 345 extends. The second leg 360 may extendupward from the first leg 358 adjacent the periphery of the head 347.

The locking cam 345 may be movable between an unlocked position (FIGS.14-16) and a locked position (FIG. 17). In the unlocked position, theflat portion 354 of the locking cam 345 may be facing the portion of theband 314 extending through the first slot 350 of the receiver 344 andmay allow the band 314 to freely move through the first slot 350. In thelocked position, the round portion 356 of the locking cam 345 may forcethe second leg 360 of the tab 346 against the portion of the band 314extending through the first slot 350, thereby clamping the band 314 inplace relative to the receiver 344. Once the band 314 has been tensionedby the tensioning device 318 (as described below) to a desired amount, asurgeon may use a screwdriver to engage slots in the head 347 of thelocking cam 345 to threadably move the locking cam 345 from the unlockedposition to the locked position.

In some embodiments, the locking device 317 may not include the tab 346,and in such embodiments, the round portion 356 may press directlyagainst the band 314 to clamp the band 314 in place. In someembodiments, the periphery of the head 347 may include a thread or oneor more annular ribs that engages one or more of the slots 326 of theband 314 when the locking cam 345 is in the locked position to fix theband 314 relative to the receiver 344.

The tensioning device 318 may include a base 370 and a tensioning screw372. The base 370 may include a pair of legs 374 and an upright portion376 that extends upward from the legs 374.

The receiver 444 may be fixedly attached to or integrallyformed with the bracket 416 and may rotatably receive the tensioningscrew 446 therein. A slot 448 may be formed in the receiver 444 throughwhich the end 424 of the band 414 may be received. A radial periphery ofthe tensioning screw 446 may engage slots 426 in the band 414 so thatwhen the tensioning screw 446 is rotated (e.g., with a screwdriver), theband 414 is advanced through the slot 448. In this manner, the band 414can be tensioned around the patient's bone and/or other tissue in themanner described above. Once the band 414 has been tensioned to adesired amount, the end 422 of the band 414 may be trimmed and/or foldedover.

With reference to FIGS. 20-25, another closure system 510 is provided.The system 510 may include a band 514, a bracket 516, a clamp 517 and atensioning device 518 (FIGS. 21-23). The band 514 and bracket 516 can besimilar to the bands and brackets described above. Therefore, similarfeatures will not be described again in detail.

One end 524 of the band 514 may be received in a channel 520 formed inthe bracket 516 and fixed therein by one or more pins (not shown),fasteners (not shown), crimping and/or any other suitable means. Theother end 522 of the band 514 may be received through the clamp 517 andthe tensioning device 518.

The clamp 517 may be a generally flat member including a pair ofapertures 527 formed therein. The apertures 527 may be aligned with apair of apertures 540 formed in the bracket 516 so that a pair offasteners 542 may be driven through the apertures 527, 540, as shown inFIGS. 23-25. As shown in FIGS. 20-25, the band 514 may be disposedbetween the clamp 517 and the bracket 516 so that when the fasteners 542are tightened within the apertures 527, 540, the band 514 may be fixedlyclamped between the clamp 517 and the bracket 516.

Prior to fixedly clamping the band 514 between the clamp 517 and thebracket 516, the band 514 may be tensioned around the patient's boneand/or tissue using the tensioning device 518. The tensioning device 518may include a base 544 and a tensioning lever 546. The base 544 mayinclude a pair of generally L-shaped legs 548 that rotatably support thetensioning lever 546 therebetween. The tensioning lever 546 may includea main body 550 having a pair of pegs 552 extending therefrom. The pegs552 may rotatably engage the legs 548 of the base 544. The tensioninglever 546 may be rotatable relative to the base 544 about an axisdefined by the pegs 552 between a first position (FIG. 21) and a secondposition (FIGS. 22 and 23). A first arm 554 (FIG. 21) may extend fromthe main body 550 in a first direction and may include first and secondtabs 556, 557 that engage the band 514. A second arm 558 may extend fromthe main body 550 in a second direction opposite the first direction andmay include an aperture 560 formed therein.

To tension the band 514 around the patient's bone and/or tissue usingthe tensioning device 518, the end 522 of the band 514 may be loopedaround the first tab 556 and under the second tab 557 with thetensioning lever 546 in the first position, as shown in FIG. 21. Theband 514 may be manually pulled taught to remove the slack in the band514 around the bone and/or tissue and so that the band 514 is fixedrelative to the first and second tabs 556, 557. Then, the tensioninglever 546 may be rotated relative to the base 544 to the secondposition, as shown in FIGS. 22 and 23. Moving the tensioning lever 546to the second position may further tighten the band 514 around the boneand/or tissue. The tensioning lever 546 can be rotated to the secondposition by gripping the first and/or second arms 554, 558 manually orwith a tool such as pliers or vice grips, for example. The tensioninglever 546 could also be rotated to the second position by inserting ascrewdriver or other tool into the aperture 560 in the second arm 558and forcing the tensioning lever 546 to the second position using thescrewdriver. With the tensioning lever 546 in the second position, thefasteners 542 can be tightened to clamp the band 514 between the clamp517 and the bracket 516, thereby fixing the band 514 in the tensionedcondition, as shown in FIGS. 24 and 25.

After tensioning and clamping the band 514, the tensioning lever 546 canbe moved back to the first position so that the band 514 can be removedfrom the tensioning lever 546 and the tensioning device 518 can beremoved from the bracket 516.

The cleats 824 may be configured so thatthe ends 815 of the band 814 can be pulled up through the centralopening 822, but the cleats 824 will move into the locked position assoon as the ends 815 begin to move back through the central opening inthe opposite direction. That is, the cleats 824 will allow the band 814to be tensioned, but will move into the locked position to prevent theband 814 from loosening, unless they are manually held in the unlockedposition.

Referring now to FIGS. 32-35, the tensioning device 818 may include abase 826, an outer tube 827, an inner tube 828, a first gripping member829 and a second gripping member 830. The base 826 may define a recess831 within which the outer tube 827 and inner tube 828 may be received.The base 826 may include feet 832 that matingly engage notches 833 inthe bracket 816, as shown in FIG. 32.

The outer tube 827 may include a spiral groove 834 formed in its innerdiametrical surface. The inner tube 828 may be received within the outertube 827 and may include a pair of axially extending grooves 835 formedthrough the inner and outer diametrical surfaces of the inner tube 828.The first gripping member 829 may be disposed within the inner tube 828and may include a pair of pegs 836 and a tapered central aperture 837.Each of the pegs 836 may extend through a corresponding one of theaxially extending grooves 835 in the inner tube 828 and slidably engagethe spiral groove 834 in the outer tube 827. In this manner, relativerotation between the outer and inner tubes 827, 828 causes axialmovement of the first gripping member 829 within the inner tube 828.That is, the pegs 836 move axially along the axially extending grooves835 as the outer tube 827 rotates relative to the inner tube 828. One ormore handles 838 (FIG. 33) may extend outward from the outer tube 827which may be gripped by a surgeon to facilitate rotation of the outertube 827 relative to the inner tube 828.

The second gripping member 830 may be disposed within the taperedcentral aperture 837 of the first gripping member 829. The secondgripping member 830 may be axially movable relative to the firstgripping member 829 between an unlocked position (FIG. 34) and a lockedposition (FIG. 35) in which ends 815 of the band 814 are gripped betweenthe first and second gripping members. When the second gripping member830 is in the locked position, upward axial movement of the firstgripping member 829 (i.e., during rotation of the outer tube 827relative to the inner tube 828) causes the first and second grippingmembers 829, 830 to pull the ends 815 of the band 814 upward relative tothe bracket 816, thereby tensioning the band 814 around the sternum 12.

With reference to FIGS. 37-39, a clamping device 900 is provided thatcan fixedly retain a band 914 and can be fixed to the patient's boneand/or any of the brackets described above, for example.

As with the tensioning device 1118, thetensioning bolt 1246 may threadably engage the base 1244 and may includea slot 1260 to engage the band 1114. With the band 1114 received in theslot 1260, rotation of the tensioning bolt 1246 relative to the base1244 may tension the band 1114 around the patient's sternum 12, asdescribed above.

The base 1246 may also include a plurality of guide apertures 1270extending therethrough. The guide apertures 1270 may be configured andarranged relative to each other so that they each may be aligned with acorresponding mounting aperture 1217 of the bracket 1216. The surgeonmay use the guide apertures 1270 as guides for drilling holes in thepatient's sternum 12 and/or driving screws 1219 through the mountingapertures 1217 into the patient's sternum 12, for example.

With reference to FIGS. 53-56, another closure system 1310 is provided.The system 1310 may include a band 1314, a bracket 1316 and a tensioningdevice 1318. The tensioning device 1318 may include a base 1344, atensioning bolt 1346, and a collar 1348. The structure and function ofthe base 1344 may be generally similar to that of the base 1144described above, apart from any exceptions described below and/or shownin the figures. Therefore, similar features will not be described againin detail.

As shown in FIG. 54, in some embodiments, the base 1344 may include oneor more slots 1345 through which the surgeon may insert a scalpel 1347or other blade for cutting the band 1314 once the band 1314 is fullytensioned and secured relative to the bracket 1316 by fastener 1325. Asshown in FIG. 55, in some embodiments, the base 1344 may include a pairof tabs 1349 that may releasably engage the bracket 1316 to secure thebase 1344 relative to the bracket 1316 during tensioning of the band1314. To release the tabs 1349 from the bracket 1316, the surgeon maysqueeze opposing sides 1350 of the base 1344 toward each other and thenleft the base 1344 upward away from the bracket 1316. In someembodiments, the tabs 1349 may include inwardly extending blades 1352that may cooperate to cut the band 1314 when the surgeon squeezes thetabs 1349 together to release the base 1344 from the bracket 1316.

Referring now to FIG. 53, the tensioning bolt 1346 may include athreaded portion 1358, an unthreaded portion 1360 and a shoulder 1361.The threaded portion 1358 may threadably engage an aperture in the base1344 (similar to the tensioning bolt 1146 and aperture 1148 of the base1144 described above). The unthreaded portion 1360 may rotatably engagean aperture 1362 in the collar 1348 so that the tensioning bolt 1346 canrotate relative to the collar 1348. The collar 1348 may include a tab1359 that is slidably received in a U-shaped recess 1357 of the base1344 to restrict relative rotation between the collar 1348 and the base1344.

The collar 1348 may include a cantilevered arm 1364 having a spike 1366thereon. The surgeon may press a free end 1324 of the band 1314 onto thespike 1366 to secure the free end 1324 relative to the collar 1348. Asthe tensioning bolt 1346 is threadably rotated relative to the base 1344(e.g., with a wrench or screwdriver) in a direction that causes movementof the tensioning bolt 1346 axially upward away from the bracket 1316,the shoulder 1361 of the tensioning bolt 1346 pushes the collar 1348axially upward with the tensioning bolt 1346, thereby tensioning theband 1314 around the patient's sternum 12.

As shown in FIG. 56, in some embodiments, the collar 1348 may include apair of fins 1370 that extend downward through the bracket 1316 andengage the sternotomy in the patient's sternum 12 to position thebracket 1316 relative to the sternotomy. The fins 1370 may be retractedout of the sternotomy as the collar 1348 moves axially upward with thetensioning bolt 1346 during tensioning of the band 1314.

With reference to FIGS. 57-60, a closure system 1410 is provided thatmay include a plurality of bands 1414 and a first bracket 1416 and asecond bracket 1417.

Thereafter, a plurality offasteners 1630 may be driven through corresponding apertures in the body1618 to secure the bracket 1616 relative to the sternum 12.

With reference to FIG. 64, another bracket 1716 is provided that may begenerally similar to the brackets 1516, 1616. The bracket 1716 mayinclude a body 1718 and a fin 1720. The body 1718 may include slots 1722that engage corresponding ends of a band 1714 that has been tensionedaround the sternum 12. As described above, the fin 1720 may be insertedinto the sternotomy 13 to align the bracket 1716 relative to thesternotomy 13.

With reference to FIGS. 65-67, another closure system 1810 is providethat may include a band 1814 and a bracket 1816. The bracket 1816 mayinclude first and second sides 1818, 1820 that are resilientlycompressible toward each other. The first side 1818 may include a firstslot 1822 that engages a first end 1824 of the band 1814. For example,the first end 1824 may be stitched around the first slot 1822.

The second side 1820 may include a second slot 1826 that slidablyreceives a second end 1828 of the band 1814. A threaded aperture 1830 inthe second side 1820 may extend into the second slot 1826. A screw 1832may threadably engage the threaded aperture 1830 and may clamp thesecond end 1828 of the band 1814 in the slot 1826 to secure the secondend 1828 relative to the second side 1820. The second side 1820 may alsoinclude a pair of arms 1834 extending therefrom. The arms 1834 mayinclude a plurality of ratchet teeth 1836.

To tension the band 1814 around the patient's sternum 12, the band 1814may be looped around the sternum 12 with the first end 1824 secured tothe first side 1818 of the bracket 1816. Then, the second end 1828 ofthe band 1814 may be inserted through the second slot 1826 in the secondside 1820 of the bracket 1816 and pulled taught around the sternum 12.Then, the surgeon may secure the second end 1828 of the band 1814 to thebracket 1816 by clamping the second end 1828 in place using the screw1832, as described above. Then, the surgeon may squeeze the first andsecond sides 1818, 1820 of the bracket 1816 toward each other usingpliers 1838, for example. The ratchet teeth 1836 on the second side 1820may engage ratchet walls 1840 of the first side 1818 to secure the firstand second sides 1818, 1820 relative to each other. At any time afterclamping the second end 1828 of the band 1814 in the second slot 1826,any access length of the second end 1828 may be trimmed, as desired.

With reference to FIGS. 68-70, another closure system 1910 and method ofclosing the sternum 12 are provided. The closure system 1910 may includea band 1914 and a pair of brackets 1916. The band 1914 may be a closedloop (i.e., a continuous loop). The brackets 1916 may be plates having apair of apertures 1920 extending therethrough. As will be subsequentlydescribed, the brackets 1916 may engage corresponding ends 1922 of theclosed-loop band 1914 and may be secured to the sternum 12 by fasteners1924 that are driven through the apertures 1920.

To close the sternum 12 using the closure system 1910, the surgeon mayfirst drill a holes 1950 in each of the portions 12 a, 12 b of thesternum 12. Then, the band 1914 may be passed into one of the holes 1950in the sternum 12 and out of the other hole 1950 so that both ends 1922of the band 1914 are exposed outside of the sternum 12, as shown in FIG.68. Thereafter, the brackets 1916 may be inserted through the loopsformed between the ends 1922 of the band 1914 and the anterior surface1952 of the sternum 12. Then, the surgeon may grip the brackets 1916 andtwist the brackets 1916 in opposite directions (or hold one bracket 1916stationary while twisting the other bracket 1916), thereby twisting theband 1914. Continued twisting of the band 1914 in this manner draws theportions 12 a, 12 b of the sternum 12 together. As shown in FIG. 70,when the sternum portions 12 a, 12 b are sufficiently drawn together,the surgeon may drive the fasteners 1924 through the apertures 1920 ofthe brackets 1916 to secure the brackets 1916 to the sternum 12.

With reference to FIG. 111, another configuration of a bracket 3516 isshown. The bracket 3516 may be relatively flexible to enable the bracket3516 to conform to the contours of the sternum (not shown) when thebracket 3516 is fastened thereto. The bracket 3516 may be any suitableshape, including, but not limited to, a circle, a square, anoval/ellipse (FIG. 111), and include a central portion 3518 extendingbetween end portions 3520. With reference to FIG. 112, in oneconfiguration, a bracket 3516 a may include a central portion 3518 athat is generally narrower than opposed end portions 3520 a. Thenarrower central portion 3518 a of the bracket 3516 a shown in FIG. 112may allow the bracket 3516 a to be readily flexed or bent to allow foroptimal positioning of the bracket 3516 a relative to the sternum.

The brackets 3516, 3516 a may include at least two apertures 3522 and achannel or groove 3524. The apertures 3522 may be located near oradjacent to the end portions 3520, 3520 a to assist with properlysecuring the bracket 3516, 3516 a to the sternum. The groove 3524 mayextend between and connect the apertures 3522. A band (not shown), orother suitable flexible element such as a wire, a string, or a cable,may be threaded through the apertures 3522 and positioned within thegroove 3524. The depth of the groove 3524 may be such that the band,when located within the groove 3524, does not extend above an outersurface 3526, 3526 a of the bracket 3516, 3516 a. In this regard, it isalso understood that a portion of the groove 3524 may extend through thebracket 3516 to form an oblong aperture (not shown). In addition toensuring proper positioning (for example, centering) of the band 3514between the apertures 3522, the groove 3524 and/or aperture (not shown)may help to ensure that the bracket 3516 is relatively flexible, thusenabling the bracket 3516 to conform to the contours of the sternum whenthe bracket 3516 is fastened thereto. The groove 3524 and/or aperture(not shown) may also help to ensure that the bracket 3516 is able to bereadily cut in case the sternum needs to reopened after installation ofthe system 10.

With reference to FIGS. 113 and 114, another closure system 3610 isshown. The closure system 3610 may include a band 3614 and a bracket3616.

The arms 3632 may extend outward from the body portion 3630, andmay include one or more apertures 3640, a channel or groove 3618, and acentral opening 3634. The channel or groove 3618 may extend between theaperture 3640 and the central opening 3634. The length of the arms 3632,and the location of the apertures 3640 with respect thereto, may be suchthat when the system 3610 is attached to the sternum 12, the location ofa force that the band 3614 imparts on the sternum 12 is adjusted by thearms 3632 and the apertures 3640. By adjusting the location of the forcethat the band 3614 imparts on the sternum 12, the bracket 3616 is ableto reduce the likelihood that the band 3614 will cut through, orotherwise damage, the sternum 12.

With continued reference to FIGS. 113 and 114, a method will bedescribed for attaching the system 3610 to the sternum 12 and tensioningthe band 3614 to reapproximate the sternum 12. The band 3614 may beinserted through the apertures 3640 a and looped around the posteriorside of the sternum 12 so that the band 3614 substantially circumscribesthe sternum 12. Once the band 3614 is looped around the sternum 12, aportion of the band 3614 may be positioned or disposed within the groove3618, and the band 3614 may be tensioned by twisting, crimping, orotherwise securing a first end 3622 of the band 3614 to a second end3624 of the band 3614. Positioning the band 3614 within the groove 3618may help to contain the band 3614 and ensure that the band 3614 remainscentered with respect to the arms 3632 a. As shown in FIG. 113, thebracket 3616 may be positioned so that the fracture separating the twoportions 12 a, 12 b of the sternum 12 is visible in the opening 3634 inthe bracket 3616 (i.e., so that two of the legs 3632 of the bracket 3616are aligned with one portion 12 a or 12 b of the sternum 12 and theother two legs 3632 are aligned with the other portion 12 a or 12 b ofthe sternum 12).
